Resolution as an active process
HypothesisResolution biology · Framework · mechanism_review
**Summary**
For decades inflammation was understood as a single process that simply "wore off" once the trigger was removed. Resolution was passive — what happened when nothing mo…
Specialized pro-resolving mediators (SPMs)
HypothesisResolution biology · Mediators · mechanism_review
**Summary**
SPMs are bioactive lipid metabolites derived from polyunsaturated fatty acids. They include four families: lipoxins (from arachidonic acid), E-series resolvins (from E…
The omega-3 index as biomarker
EvidenceResolution biology · Markers · mechanism_review
**Summary**
The omega-3 index measures EPA + DHA as a percentage of total fatty acids in red blood cell phospholipids. It is the standardized, clinically-validated proxy for tissu…
MUC2 glycosylation — the structural key
HypothesisMucosa · Architecture · mechanism_review
**Summary**
MUC2 — the dominant secreted mucin in the colon — is not protein with sugar attached. It is, by weight, mostly sugar. Up to eighty percent of the molecule's mass is it…
Resolution biology — SPMs (resolvins, protectins, maresins)
HypothesisMucosa · Adjacent systems · mechanism_review
**Summary**
Conceptually one of the most important paradigm shifts in inflammation research in the past 15 years, led by Charles Serhan at Harvard. Resolution of inflammation is n…
The sepsis-permeability feedback loop
HypothesisMucosa · Mechanisms of dysfunction · mechanism_review
"Leaky gut → sepsis" is not a one-way mechanism. It is a self-reinforcing cycle.
Both leaky gut (barrier defect at intestinal surface) and gut dysbiosis are intrinsic to sepsis. W…
Akkermansia muciniphila and the mucolytic balance
HypothesisMucosa · Microbiome interface · mechanism_review
Akkermansia muciniphila colonizes the mucosal layer of the human gut. It is particularly effective at increasing mucus thickness and improving barrier function. A. muciniphila rest…
Paneth cells and α-defensins (HD5, HD6)
HypothesisMucosa · Architecture · mechanism_review
The small intestine has its own specialized defense system: Paneth cells at the bottom of the crypts of Lieberkühn, which produce potent antimicrobial peptides — particularly HD5 a…
Mast cells and mucus hypersecretion (MCAS)
HypothesisMucosa · Adjacent systems · human_observational
Mast cell activation syndrome (MCAS) is a differential consideration in any picture combining inflammation escalation, mucus hypersecretion, and food intolerance patterns.
Mast ce…
The vagus nerve and the cholinergic anti-inflammatory pathway
HypothesisMucosa · Adjacent systems · mixed
The vagus nerve has anti-inflammatory properties through its afferents (activating HPA) and its efferents (the cholinergic anti-inflammatory pathway, CAP). The CAP inhibits pro-inf…
The glycocalyx and heparan sulfate / syndecan-1
HypothesisMucosa · Architecture · mechanism_review
A third barrier system, often overlooked in clinical discussion: the glycocalyx layer on the basolateral side of enterocytes, primarily based on heparan sulfate proteoglycans (espe…
Dietary emulsifiers and mucus barrier damage
HypothesisMucosa · Interventions · mixed
Specific food additives have surprisingly strong evidence for mucus barrier damage.
Consumption of generally-regarded-as-safe emulsifiers has increased, and is associated with inc…
The integrated mechanistic model
SpeculationMucosa · Synthesis · mechanism_review
When all of this is integrated, a pattern emerges that may match many escalating mucosal-disease pictures.
**The primary lesion (hypothesis):** defective mucin glycosylation — eit…
